Freelin-Wade | 1/4" DOT Nylon Tube, Red | 1J-223-05

Key Properties:
- 1/4" outer diameter (OD) nylon tubing, DOT-223 series.
- Manufactured by Freelin‑Wade as “Nylon DOT ‘A’ Tubing”.
- The tubing is made from nylon (polyamide) — giving it good heat resistance, chemical and abrasion resistance, and dimensional stability.
- Temperature rating: approximately –60 °F to +200 °F (–51 °C to ~93 °C).
- Vacuum rating: to 28″ Hg.
- Compatible with push-in or compression-type fittings.
- Offers a high pressure safety margin (standard tubing built with a 4:1 safety factor according to manufacturer docs) for pneumatic / fluid applications.

Common Applications:
- Pneumatic air lines (e.g. for compressed air systems, air brakes) — “DOT”-rated tubing suitable for vehicular or industrial pneumatic systems.
- Hydraulic or vacuum lines where nylon’s chemical and abrasion resistance is advantageous.
- Chemical processing, oil/fluid transport, or lubricant delivery systems requiring corrosion- and chemical-resistant tubing.
- Automation / robotics / manufacturing equipment pneumatic tubing, where flexibility, reliability and resistance to environmental factors (heat, UV, chemicals) matter.
- General industrial fluid or gas transfer lines — as a lightweight alternative to metal tubing when appropriate.
